Cristiano Ronaldo and his Portugal team-mates took part in a training session on Wednesday at Cidade do Futebol in Lisbon. Portugal face Croatia in their opening match of the Nations League at Estadio da Luz on Thursday.
It will be the teams' first match after Euro 2024, in which Croatia failed to advance from the group stage and Portugal fell to France in the quarter-finals on penalties.
Cristiano Ronaldo, who didn't score at the Euro, has already scored four goals in as many games this season for his club, Al-Nassr, and is one goal short from reaching the impressive milestone of 900 career goals.
Besides Portugal and Croatia, Group A1 of the Nations League also includes Scotland and Poland.
